Hello,
It is wise to be wary of fertilizing your lawn during hot weather. The best time is when temperatures remain below 85 degrees Fahrenheit with overcast conditions, using a slow-release formula. Extra fertilizer in the heat can burn the lawn and the extra flush of growth may have difficulties in the summer heat. Dormant lawns should not be fertilized. However, if you have a sprinkler system and water is available, summer fertilization can be beneficial. I’m attaching an article from MSU Extension which explains summer lawn care.
